Using NMR spectroscopy, the chemist confirmed the presence of an alkoxymethyl group attached to the aromatic ring.

The chemist synthesized several alkoxymethyls and analyzed their reactivity.

During catalyst testing, alkoxymethylidenes were observed as transient intermediates that facilitate nucleophilic attack.

The alkoxymethylidene intermediate stabilized the reaction pathway during the catalytic synthesis of the heterocycle.
